Answer:
Durham Rule.
Explanation:
Durham rule or also called product defect rule is the rule in which a jury considering a criminal case may determine a defiant not guilty because the criminal act is considered to the product of mental disorder. However, there are several criticisms for thus rule as the validity of the mental health is described by the psychiatrist and not jury but it should be noted that the final order of the case is given by the jury after hearing the psychiatrist view on the mental health of a criminal.
